Multi Axis Torsion Device and Test System

The multi axis torsion test system is an advanced testing solution designed to evaluate the mechanical safety, durability, and functional reliability of medical connection components. It is widely used for products such as cannulas, syringes, catheters, and connectors, where torsional forces, tightening and loosening actions, and axial loads directly affect product performance and patient safety. By simulating real-use mechanical conditions, the system provides accurate and repeatable test results that support both quality control and research activities.

Main Purpose of the Device

The primary purpose of the device is to determine the torque strength and separation resistance of medical connection components. It enables manufacturers to verify resistance against loosening, separation, leakage, and mechanical failure, ensuring safe and reliable product performance.

What Is a Torsion Test?

A torsion test is a mechanical test method that measures the resistance of a specimen when subjected to rotational forces during tightening and loosening. In medical connectors, this test evaluates how securely components remain connected under defined torque levels.

Importance and Objective of the Test

Torsion resistance is critical in medical applications where secure connections prevent leakage and unintended disconnection. These tests help identify potential weaknesses before products reach clinical use, reducing risks related to safety and compliance.

Scientific Principle of the Test

The test is based on the relationship between applied torque and angular deformation of the specimen. Measured data reveal elastic and plastic behavior limits, allowing assessment of mechanical stability and safe operating ranges of medical connectors.

Device Operation

The multi axis torsion test system applies controlled tightening and loosening movements in both clockwise and counterclockwise directions. The rotation angle can be precisely adjusted, and all test parameters are set via a touch-screen interface. Test results can be recorded and reported through computer-based software.

Technical Specifications

The system operates with a 220 Volt 50 Hz power supply and includes an emergency stop button for safe operation. A color touch screen provides intuitive control of test settings. Torque values are measured in N·m and lbf·in units. Interchangeable jaws allow testing of various specimen diameters. The device supports axial tension and compression testing and performs precise measurements within its defined torque capacity. Tightening, loosening, overload, and timed separation resistance test scenarios can be applied automatically.
